Grimes Boulevard and continuing to the East WWTP. Walker Partners was recently selected as the most qualified firm to perform engineering services for this project and will assist the partners in evaluating options to increase capacity and address rehabilitation needs for the portion of this Brushy Creek Interceptor.
This item is for the approval of an Interlocal Agreement (ILA) between the City of Round Rock, City of Cedar Park, City of Austin, and City of Leander, for the allocation of costs for design of the expansion and rehabilitation of a portion of the Brushy Creek Regional Interceptor. The project cost allocations are based on flow projections for the year 2040. The City of Round Rock’s cost allocation is 53.33%. Under the ILA, the City of Round Rock staff will manage the proje...
